project leader.,Zhou Yanfei,，,deputy chief designer of Chinas manned space programme,，,said on Friday that China wishes to use the manned lunar missions to carry out scientific surveys and technology demonstrations,，,explore ways to develop lunar resources and strengthen the nations space capabilities.,“,A new wave of lunar explorations has been emerging in the world,，,with participants aiming to make sustainable missions to deepen knowledge of the moon and exploit resources there,，”,he said in a report delivered at the 2020 China Space Conference in Fuzhou,，,Fujian Province.,“,Unlike other nations,，,China must depend on its own science and technology to realise our goals.,”,The country is independently able to land its astronauts on the moon because it has the technologies,，,a group of well,trained,innovative professionals and high,efficiency research and management systems,，,Zhou said.,“,However,，,our existing,carrier rockets cant perform landing missions to the moon because they are not powerful enough.The Shenzhouseries manned spaceships are not suitable for lunar expeditions.We dont have a lunar landing capsule,，”,he said.,“,Our ground support system was designed for operations in Low Earth orbit rather than on the lunar surface.,”,To solve the problem,they set out to produce a powerful launch vehicle.Zhou said researchers thought about two approaches,making a new heavy,lift rocket,，,or adjusting the next,generation rocket designed to carry astronauts,，,which is,under development.Researchers prefer the latter approach because it would be easier to design and make and would become operational earlier.,The new rocket is being designed at the China Academy of Launch Vehicle Technology.Its main body will be 87 metres tall,，,with a diameter of 5 metres,，,which would make it almost twice as tall as the Long March 5,，,currently the biggest of Chinas rockets.,(,)1,What is the main idea of Paragraph 4?,A,China is not capable of pursuing the manned

around the craters,generate wireless power for future,infrastructure,and enable autonomous mobility even in the most extreme environments.The research results could benefit NASAs Artemis Programme and be used to study the moon ahead of a human landing in 2024 or help establish a sustained presence by 2028.Each team will receive different amounts of,grants,_based on the concept and budget they propose.They will develop and test the technologies in simulated(,模拟的,)environments with the awards during the following 10 months,showing they are prepared for a possible lunar mission as early as 2023.,“,One of the most exciting things about this challenge is that,several of the concepts,if proven to be valuable as a result of these awards,could eventually be integrated and operated together
